Client Highlights

Since 1971, Dave Strassman has owned and operated DRS Asphalt Paving, an asphalt paving contractor and asphalt wholesaler. Apart from the world of asphalt, anybody who has crossed paths with Dave knows two things about him:  1) he tinkers with and  re-engineers almost everything he touches; and  2) he is fiercely committed to the welfare of America’s  wounded veterans.

Those two qualities are most aptly on display in Dave’s  U.S. Pat. No. U.S. Pat. No. 8,201,653 – “Seats for  self-balancing vehicles.” The patent covers seats for use on  Segway-type,  self-balancing vehicles so that the vehicle can be driven by amputees or those with compromised leg strength. Through the  non-profit program Segs4Vets, these modified vehicles are provided to our wounded warriors free of charge. The website for Segs4Vets states its motivation  most elegantly:

Segs4Vets is an unprecedented  grass-roots effort sustained and administered by volunteers representing grateful Americans, who passionately believe that when those serving our nation are sent into harm’s way and suffer serious injury and permanent disability they must have every resource and tool available to them, which will allow them to fulfill their dreams and live the highest quality of  life possible.”
